how to automatically create the associated schema when I `pg_restore` a table?

Question

I backed a table into a file using something like pg_dump --table=ex.tab.

But when I restore the dump file into a newly created database, it complains that the schema ex does not exist. Looking into the dump file ( listed below), it does not have a CREATE SCHEMA statement.

Is there an option that I can add to pg_dump or pg_store so that the schema of the table is automatically created?

Note: I do this for multiple tables in the command line (multiple --table=), and do not want to manually create schema for each table beforehand (if possible).

Use pg_dump --schema option for this.

With:

$ psql
psql (9.4.19)
Type "help" for help.

mevzek=# CREATE SCHEMA test1;
CREATE SCHEMA
mevzek=# CREATE TABLE test1.atable (id SERIAL);
CREATE TABLE
mevzek=# \q

You can compare the results of the two commands:

$ pg_dump --table test1.atable > dump1.sql
$ pg_dump --schema test1 > dump2.sql
$ diff -u dump1.sql dump2.sql
--- dump1.sql   2019-07-18 12:55:53.000000000 -0500
+++ dump2.sql   2019-07-18 12:56:59.000000000 -0500

 SET default_tablespace = '';

 SET default_with_oids = false;

If you add --table it does not seem to create the schema anymore. You could go around that with two commands: pg_dump --schema test1 --exclude-table-data '*' and then pg_dump --table test1.atable --data-only or similar.
